A baby girl is in a stable condition in a Hunter hospital with a suspected case of meningococcal disease.

Antibiotic treatment has been arranged for the child’s close contacts as a precaution to prevent spread of infection.

So far there have been six confirmed cases of meningococcal disease in Hunter New England Health region this year.

In 2006 there were 12 cases of meningococcal disease in the Hunter New England Health region, 13 cases in 2005 and 24 cases in 2004.

Hunter New England Health Public Health Physician Dr David Durrheim said seeking medical attention quickly could help prevent the development of serious complications.

"If anyone suspects meningococcal disease, they should seek medical attention immediately," Dr Durrheim said.

Meningococcal disease has a sudden onset and symptoms may include:

"Meningococcal infection does not spread easily," Dr Durrheim said.

"It is spread by secretions from the nose and throat of a person who is carrying it and close and prolonged contact is needed to pass it on.

"It does not appear to be spread through saliva or by sharing drinks, food or cigarettes."

He stressed that while meningococcal disease could be serious, in most cases, early detection and treatment resulted in a complete recovery.
